Get PDFGoing Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
KRASG12C mutant lung adenocarcinoma: unique biology, novel therapies and new challenges
Get PDFKRAS mutant lung cancer is the most prevalent molecular subclass of adenocarcinoma (LUAD), which is a heterogenous group depending on the mutation-type which affects not only the function of the oncogene but affects the biological behavior of the cancer as well. Furthermore, KRAS mutation affects radiation sensitivity but leads also to bevacizumab and bisphosphonate resistance as well. It was highly significant that allele specific irreversible inhibitors have been developed for the smoking associated G12C mutant KRAS (sotorasib and adagrasib). Based on trial data both sotorasib and adagrasib obtained conditional approval by FDA for the treatment of previously treated advanced LUAD. Similar to other target therapies, clinical administration of KRASG12C inhibitors (sotorasib and adagrasib) resulted in acquired resistance due to various genetic changes not only in KRAS but in other oncogenes as well. Recent clinical studies are aiming to increase the efficacy of G12C inhibitors by novel combination strategies
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Személyre szabott kezelés nem-kissejtes tüdőrákban – a diagnosztikától a terápiáig = Personalized Treatment in Non-Small Cell Lung Cancer: From Diagnostics to Therapy
Get PDFA molekuláris célzott terápia – a lehetőségek bővülésével – egyre inkább szerephez jut a tüdőrákos betegek ellátásában. Ezzel együtt rendkívül fontossá vált a daganatnak nemcsak a pontos szövettani tipizálása, hanem molekuláris jegyeinek feltérképezése is. A rutin klinikai gyakorlatban citotoxikus kezelésnél betegszelekció céljából prediktív szöveti markereket még nem alkalmazunk, azonban egyre bővülnek azok a kutatási eredmények, amelyek segíthetik az onkológusokat abban, hogy egyszer majd a betegeiket egyénre szabott kemoterápiában részesíthessék. Különösen megnőhet ennek jelentősége akkor, amikor a beteg életkora, általános állapota és/vagy társbetegségei miatt a kemoterápiának még az alkalmazhatósága is megkérdőjeleződik. A tüdőrák molekuláris célzott terápiája manapság elsősorban az adenocarcinomában szenvedőknek ad reményt, az intenzív kutatások eredményeképpen azonban már körvonalazódnak további ígéretes terápiás célpontok. Napjainkban az onkopulmonológia forrongó korszakának lehetünk szemtanúi, ami minden nehézsége ellenére a tüdőrákban szenvedők és kezelőorvosaik számára egyaránt reményekkel szolgál.
Molecular targeted treatment, with broadening opportunities, plays an important role in the management of lung cancer patients, which renders molecular mapping of the tumor tissue crucial. In case of cytotoxic chemotherapy, there is no patient selection according to tissue biomarkers; however, there are expanding results that might help oncologists to use personalized chemotherapy in the near future. This may be of great importance when patients’ age, performance status and/or co-morbidity make the applicability of chemotherapy uncertain. Nowadays, molecular targeted treatment gives hope mainly for patients with adenocarcinoma; however, promising therapeutic targets have already been outlined due to intensive research. In these days, we are experiencing a turbulent era of oncopulmonology, which – despite all difficulties – gives hope for both patients and clinicians
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
